strftime
For Windows user! It's rather the same as strptime!
It uses the previous function: but call strToTime($date, $format) to strToDate($date, $format) because this name is forgiven!
<?php
function strToDateTime($date, $format) {
if(!($date = strToDate($date, $format))) return;
$dateTime = array('sec' => 0, 'min' => 0, 'hour' => 0, 'day' => 0, 'mon' => 0, 'year' => 0, 'timestamp' => 0);
foreach($date as $key => $val) {
switch($key) {
case 'd':
case 'j': $dateTime['day'] = intval($val); break;
case 'D': $dateTime['day'] = intval(date('j', $val)); break;
case 'm':
case 'n': $dateTime['mon'] = intval($val); break;
case 'M': $dateTime['mon'] = intval(date('n', $val)); break;
case 'Y': $dateTime['year'] = intval($val); break;
case 'y': $dateTime['year'] = intval($val)+2000; break;
case 'G':
case 'g':
case 'H':
case 'h': $dateTime['hour'] = intval($val); break;
case 'i': $dateTime['min'] = intval($val); break;
case 's': $dateTime['sec'] = intval($val); break;
}
}
$dateTime['timestamp'] = mktime($dateTime['hour'], $dateTime['min'], $dateTime['sec'], $dateTime['mon'], $dateTime['day'], $dateTime['year']);
return $dateTime;
}
?>
Descrição
array strptime
( string $date
, string $format
)
strptime() returns an array with the date parsed, or FALSE on error.
Month and weekday names and other language dependent strings respect the current locale set with setlocale() (LC_TIME).
Parâmetros
- date (string)
-
The string to parse (e.g. returned from strftime())
- format (string)
-
The format used in date (e.g. the same as used in strftime()).
For more information about the format options, read the strftime() page.
Valor Retornado
Returns an array, or FALSE on failure.
| parameters | Description |
|---|---|
| tm_sec | Seconds after the minute (0-61) |
| tm_min | Minutes after the hour (0-59) |
| tm_hour | Hour since midnight (0-23) |
| tm_mday | Day of the month (1-31) |
| tm_mon | Months since January (0-11) |
| tm_year | Years since 1900 |
| tm_wday | Days since Sunday (0-6) |
| tm_yday | Days since January 1 (0-365) |
| unparsed | the date part which was not recognized using the specified format |
Exemplos
Exemplo #1 strptime() example
<?php
$format = '%d/%m/%Y %H:%M:%S';
$strf = strftime($format);
echo "$strf\n";
print_r(strptime($strf, $format));
?>
O exemplo acima irá imprimir algo similar a:
03/10/2004 15:54:19 Array ( [tm_sec] => 19 [tm_min] => 54 [tm_hour] => 15 [tm_mday] => 3 [tm_mon] => 9 [tm_year] => 104 [tm_wday] => 0 [tm_yday] => 276 [unparsed] => )

If strptime() fails to match all of the format string and therefore an error occurred the function returns NULL.

The result of strptime() is not affected by the current timezone setting, even though strftime() is. Tested in PHP 5.1.6.

If you need strptime but are restricted to a php version which does not support it (windows or before PHP 5), note that MySQL since Version 4.1.1 offers (almost?) the same functionality with the STR_TO_DATE function.
See http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html

<?php
//This turns non-standard but often used "datetime" string
//like '20060810084251' into nice formatted date

//note, that strptime returns day of year counting from 0, so
//you need to put 1 as month number to get appropriate
//month for the daycount. for 2006 strptime for unknown
//reason returns 106, so I simply add 1900

It says "Parse a time/date generated with strftime()" but that's not entirely correct -- While strptime("2006131", "%Y%W%u") works as expected, strptime("2006131", "%G%V%u") returns false instead of reversing the equivalent - and unambiguous - strftime() usage. I suspect that's because glibc doesn't support that. Anyway, this docu page fails to mention that apparently not all format components supported by strftime() can be used with strptime().
